UNLABELLED Preoperative injection of radiocolloid for axillary sentinel node biopsy in breast cancer is uncomfortable for patients. This study evaluated the reliability of radiocolloid injection as determined by sentinel node identification rate and positive sentinel node biopsy rate, after the patient has been anesthetized in the operating room as compared with preoperative injection. METHOD...

The presence of axillary nodal metastases has a significant impact on locoregional and systemic treatment decisions. Historically, all node-positive patients underwent complete axillary lymph node dissection; however, this paradigm has changed over the last 10 years. The use of sentinel lymph node dissection has expanded from its initial role as a surgical staging procedure in clinically node-n...

AIMS AND BACKGROUND We studied the potential use of sentinel lymph node identification using a near-infrared fluorescence imaging technique in the treatment of cervical cancer. METHODS AND STUDY DESIGN Directly before the start of the operation, 0.2 ml of 5 mg/ml indocyanine green was prepared and injected into 4 sites in the cervix using a 26-gauge standard needle, at 3, 6, 9 and 12 o'clock ...

BACKGROUND The effect of sentinel lymph node status on survival in patients with Merkel cell carcinoma (MCC) of the head and neck is uncertain. METHODS We used the Surveillance Epidemiology and End Results (SEER) database to identify patients with MCC who underwent sentinel lymph node biopsy (SLNB). Clinicopathologic data and disease-specific survival (DSS) were compared among patients with p...

OBJECTIVE To evaluate the value of sentinel lymph node biopsy in diagnosis of cervical metastasis in patients with early oral squamous cell carcinoma. METHODS Cochrane library, evidence-based medicine (EBM), PubMed, China national knowledge internet (CNKI) were searched for 2001 - 2011 literatures on sentinel lymph node biopsy in patients with oral squamous cell carcinoma as early diagnosis o...

A. This guideline is written specifically for lymphoscintigraphy in patients with primary melanomas that originate in the skin. Staging of these tumors is based on tumor thickness (Breslow measurement) and level of skin invasion (Clark’s level), both of which are determined by the pathologist from a biopsy sample. Ample data correlate patient survival with Breslow and Clark measurements. In the...

AIMS To evaluate the accuracy of sentinel lymph node biopsy in breast cancer patients at this institution, using combined technetium-99m ((99m)Tc) sulphur colloid and patent blue vital dye. METHODS From March 2007 to July 2008, 50 patients with a tumour of less than 3 cm and with clinically negative axillary lymph nodes underwent sentinel lymph node biopsy (SLNB), followed by axillary lymph n...

Objective The aim of this study was to establish the effectiveness of sentinel lymph node biopsy in the detection of metastasis in N0 necks of T1-T2 early-stage oral cavity cancers. Materials and Methods Twenty neck dissections were performed in 18 patients diagnosed with T1 and T2 oral cavity cancer, with an indication for elective neck dissection between November 2007 and January 2011. The ...

BACKGROUND Sentinel lymph node biopsy remains controversial for cutaneous melanoma of the head and neck (CMHN). Incidence and factors associated with recurrence after negative sentinel lymph node biopsy have not been well delineated. METHODS Characteristics of 204 patients with head and neck melanoma who had a negative sentinel lymph node biopsy were studied. Main outcomes were overall surviv...

Background: Sentinel lymph node biopsy in early breast cancer performed by intraparenchymal or intradermal injection of blue dye and/or radioactive colloid remains a highly acceptable method of identifying sentinel nodes largely because of its success rate. Aim: 1. To assess the efficacy of sentinel lymph node biopsy in detecting axillary metastases in cases of node negative early breast cancer...
